anaemic RAILWAY-SWITCH SIGNALING DEVICE.

Specification of Letters Iatent.

Patented J line 27, 1916.

' Application filed June 1, 1914. Serial No. 842,287.

switch blade of a steam or electric railroad switch signal and on near the pointthereof and connecting the said device by electric wires on one hand to the red and white lights of the electric the other to the .feed wire for electric current.

The object of my improvement is toprovide a device which can beattached to any railway switch blade nearthe point thereof, and which is further attached with electric wires with the red and white lights of an. electric switch signl onl' the one hand, and with the feed wire for electric current on the other, so that when moved to and fro by opening and closing the switch, said device automatically. makes contact and thereby produces a red or"white light in the switch signal.

I attain these ob ects by Y the mechanism illustrated in-the accompanying drawing.

' Figure 1 is aperspective view of the entire device. Fig. 2 is a View of the railway track of a steam. or electric road showing how the electric signaling device may be att'ached,-when in use, to the railroad tie and to the switch blade, and also showing the position of wires running to switch signal lights and the feed wire for current.

A. is the sliding arm with a nut to fasten it to the switch blade which arm is insulated from the contact blade. I

B. is the sliding contact blade.

' C. is a contact prong for the white light of the switch signal. I). is the contact prong for the ground wire or neutral wire and is neutral to Cor E. E. is a contact prong for the red light of the switch signal. F. is the insulated base which said contact prongs C, D and E are mounted on and in sulates these contact prongs from the cast iron box H.

the switch blade is blade is moved endwise in Gnis the insulator which insulates the contact blade from the sliding arm A.

H. is a cast iron box which supports the switch signaling device and also protects it 'from the weather and other damages that might happen to it. I. is the cast iron cover to said box H.

J. is an electric wire which runs to the red light ofthe switch signal which ma be located at the switch or anywhere desired.

K..is the neutral wire for both red and white lights.

L. is an electric wire which runs to the white light of the switch signal.

When theswitch blade is moved in opening or closing the switch. the sliding arm attached to said switch blade likewise is moved and [thereby automatically I changes contact producing a red or white lightas the caseniay be. V

1 claim for my invention:

Ina circuit changing switch, a carrying barof polygonal cross section, polygonal bearmgs Qurnal'ing said bar to limit the latter to linear movement and prevent rotarymovement of said bar, means. for moving said bar to and fro to predetermined positions, a flat Straightswitch blade ha ring. one side'edge rigidly secured to said 'lnuz'a plurality of alined. spring terminal contact clips for electrical engagement with the rcmalnlng. margin of said blade on opposite sides thereof. and having their longitudinal axes at right angles to the direction of movement of the blade, one of said clips being in constant sliding engagement with a central portion of said blade. the remaining or end terminals being spaced apart irom the central terminal "sullicicntly with respect; to the length of said switchblade to cause the latter to close circuit between said central and the end terminal toward which the one position. and open circuit with respect to the remaining or otherend terminal. and ice rcrsa. substantially as dwcribed.
